Abstract

The invention discloses special synergistic chelated fertilizer for topdressing of Lycopersicon esculentum and a preparation method of the synergistic chelated fertilizer. The synergistic chelated fertilizer is prepared from 15-30 parts of urea, 5-20 parts of monoammonium phosphate, 40-65 parts of potassium sulfate, 1-8 parts of tapioca flour, 1-1.5 parts of humic acid, 0.5-1 part of ammonium polyphosphate, 0.2-0.3 parts of ferrous sulfate heptahydrate, 0.1-0.2 parts of manganese sulfate monohydrate, 0.1-0.2 parts of zinc sulfate heptahydrate, 0.1-0.15 parts of boric acid, 0.02-0.05 parts of thiourea and 0.01-0.02 parts of compound sodium nitrophenolate. The formula of the synergistic chelated fertilizer is scientific and reasonable according to growth characteristics of the Lycopersicon esculentum in flowering and fruit bearing stages, nutrient availability is high, demands of the Lycopersicon esculentum for macroelements and microelements can be met, and the fertilizer further has the effects of promoting growth of Lycopersicon esculentum fruits and improving fruit quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular the invention relates to a special synergistic chelate fertilizer for tomato topdressing and a preparation method thereof. Background technique [0002] Tomatoes (Lycopersicon esculentum Mill.) are rich in nutrients such as vitamin C, carotene, and lycopene. They have a special flavor and can be eaten raw or cooked. Tomato is an important economic crop, which is widely cultivated in the north and south of my country, and the cultivation area is still expanding. Cultivating tomatoes requires balanced application of nitrogen, phosphorus, potassium and trace elements, especially during the flowering and fruiting period of tomatoes, the demand for nitrogen, phosphorus, and potassium of tomatoes rises sharply, especially the role of potassium and trace elements appears at this time Especially important, rational application of potassium fertilizer and trace elements can effectiv...
